My dealer told me it was the pump for the headlight washer that was leaking and that it would be about $450 to replace. Mine is still leaking but it seems to leak less frequently if I use the washers more often. I like the sound of a $35 fix better than a $450 fix.

I don't have an extended warranty. I just know that it leaked the windshield cleaning fluid in fairly short order and I had it checked out at the dealer. I ended up just refilling the reservoir and then using the thing a couple of times a week and it has not leaked again. I would rather spend a few bucks on fluid than $450 on a new pump.
